Tuna, the famous miniature chiweenie with a major overbite, has a stiffer rider for appearances than many human A-listers.

The 8- pound, comedic-looking dog with 1 million Instagram followers will appear at the Strand Book Store on Tuesday to promote his new book, “Tuna Melts My Heart: The Underdog With the Overbite.” But guests must adhere to rules including “no flash photography,” “no photos with Tuna” and “no touching” the famous pup, whom owner Courtney Dasher rescued four years ago from an LA farmers market.

Strand events director Emily Simpson says the rules, stipulated by Tuna’s publicist, are for the dog’s safety: “The last thing you want to do is stress a pet out at the event.”
